WARNING
To prevent an electric shock, take the following precautions:
1. Before wiring:
A. Disconnect the power supply.
B. Open the door and wedge the door open.
C. Discharge the high voltage capacitor and wait for 60 seconds.
2. DO NOT let wire leads touch to the following parts:
A. High voltage parts: Magnetron, High voltage transformer, High voltage capacitor and High
voltage rectifier assembly.
B. Hot parts: Oven lamp, Magnetron, High voltage transformer and Oven cavity.
C. Sharp edge: Bottom plate, Oven cavity, Waveguide flange, Chassis support and other metallic
plates.
D. Movable parts (to prevent a fault) Fan blade, Fan motor, Switch, Switch lever, Open button.
3. Do not catch the wire leads in the outer case cabinet.
4. Insert the positive lock connector completely until its pin is locked. Make sure that the wire leads
should not come off even if the wire leads are pulled.
5. To prevent an error function, connect the wire leads correctly, referring to the Pictorial Diagram.
WARNING
Avoid possible exposure to microwave energy. Please follow instructions below before operating oven.
1. Disconnect the power supply cord.
2. Make sure that a definite" click" can be heard when the microwave oven door is unlatched.
(Hold the door in a closed position with one hand, then push the door open button with
the other, this causes the latch leads to rise, it is then possible to hear a "click' as the door
switches operate.)
3. Visually check the door and cavity face plate for damage (dents, cracks, signs of arcing etc.).
Carry out any remedial work that is necessary before operating the oven.
Do not operate the oven if any of the following conditions exist;
1. Door does not close firmly.
2. Door hinge, support or latch hook is damaged.
3. The door gasket or seal is damaged.
4. The door is bent or warped.
5. There are defective parts in the door interlock system.
6. There are defective parts in the microwave generating and transmission assembly.
7. There is visible damage to the oven.
Do not operate the oven:
1. Without the RF gasket (Magnetron).
2. If the wave guide or oven cavity are not intact.
3. If the door is not closed.
4. If the outer case (cabinet) is not fitted.
CAUTION
Disconnect oven from power supply before removing outer case. Discharge high voltage capacitor
before touching any oven components or wiring after removing outer case.
